The paper discusses the design and testing of a smart aeroelastic model of a suspended bridge that allows active regulation of torsional damping through the use of embedded piezoelectric actuators. Depending on test conditions, the structural damping of the model can be adjusted in a fast, precise and repeatable way in order to highlight the effects of the wind interaction. In particular, vortex-induced vibrations are taken into consideration. The main elements of the smart structure (sensors, actuators, control algorithm) have been designed on the basis of a numerical model of the system. Finally the aeroelastic model has been tested in a wind tunnel in different operating conditions and its dynamics have been assessed.
